CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 720,949, dated February17, 1903.

flerial No. 116.506. (No model.)

To all whon t it may concern.-

Be it known that I, WILLIAM J. MOCULLEY, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Oar-Roofs, of which thefollowing is a specification, reference beinghad therein to the accompanying drawings.

. The invention relates to a car-roof composed of a multiple of metallicplates or sections designed as a covering for the wooden roofs offreight-cars; and it consists in the particular construction of thesections, the joint or connection between the sections, and in theconstruction of a cap for the peak-joint and a connection between suchcap and the sleeper which constitutes a support for the runningboards,all as more fully hereinafter described, and particularly pointed out inthe claims.

In the drawings, Figure l is a sectional perspective view showing myimproved roof applied to a freight-car. Fig. '2 is a plan view thereof,showing part of the plates of the roof in position as in the course ofbuilding the roof. Figs. 3 and 4 are perspective views of the two platesfrom which I preferably make my roof. Fig. 5 is a section through thepeak-joint, showing the parts in position ready tobe connected together.Fig. 6 is a perspective view of the peak-cap and the hook-plate thereon.Fig. 7 is a section through the peak-cap, showing the hook of the hookedplate engaged with the sleeper for the runhing-board.

A designates the board covering of an ordinary freight-car supportedupon the purlins B, and 0 represents the oarlines.

D is the ridge-timber, and E designates the plates.

F and F are the metallic plates of which my roof is formed. The plate Fis provided at two edges with flanges which extend parallel with theside edge thereof, and in this particular embodiment of my invention Ishow the flanges in the form of a double inverted trough a a, with thegutter b. At the lower edge is a flange 0, adapted to extend down theside of the plate and be secured thereto, preferably with a bead orflexible portion d therein to allow a slight movement of the plate Fwithout danger of breaking it.

The plate F is provided upon two edges with the double spring-hooks e 6.These hooks e e are of a size to engage over the flanges upon the plateF and when engaged thereover to spring upon the flanges of the plate Fand be clamped'thereon by the spring action of the hooks e e. I refer tothe hooks e e as double hooks, because they are, in efiect, a hook ateach edge, which engage with and grip beneath the edges of the flangeson the plates F and F, as plainly shown in Fig. 1.

Instead of making the two plates F and F with differing flanges I maymake the plates both like the plate F. Except as hereinafter described Iprefer the construction with the two kinds of plates.

In laying the roof the plates F and F will alternate upon oppositesidesof the peak, as shown in Fig. 2, the flange along the upper edge thereofextending along the peak, while the flange along the side will extendfrom the peak transversely of the roof to the lower edge thereof. Theplates F are then laid upon the roof with their flanges sand 6overlapping the flanges of the plates F and are forced thereover fromthe position shown in Fig. 5 to that shown in Fig. 1, the spring of themetal permitting this, and when engaged, as shown in Fig. 1, the doublehook of the flanges e 6 will engage in the hooks or recesses upon theedge of the flanges of the plate F and tightly clamp the parts together.

By making the gutter b in the flanges of the plates F any water that maybe driven by heavy winds up under the edges of the flanges will becarried in the gutter to the lower edge of the roof and fall off at theside. This construction of joint between the plate-sections formsaflexible interlocking joint, permittin g a slight movement of the platesin relation to each other by the flexing of the metal without danger ofinjuring the joint and at the same time producing a water-tight jointbetween the plate-sections.

In order to cover-the opening H at the intersection of the plates on thepeak, I provide the caps I, having the intersecting radiallyextendingchannels 7?. fitting over the interlocking flanges or hooks of theplates and extending a short distance thereover, so as to prevent theadmission of water through the roof at that point. This plate or cap isprovided with a central aperture J, through which is passed aclamping-bolt K, passing through the ridge-timber D and acting to holdthe entire metallic roof in position. In order to cover the bolt-openingJ, I provide a supplemental cap L, having a dovetail groove on its underface, which is adapted to engage the dovetail flanges M upon the upperface of the cap I.

In order to secure the sleepers O,upon which the running-boards aresecured, without necessityiof bolts through the roof, I provide thesupplemental cap L with ahook P, adapted to engage in the notch Q in theupper middle portion of the sleepers O, as plainly shown in Fig. 7, thesleeper abutting at one edge against the cap-plate and being held frommovement in the other direction by the hook P. As this sleeper hasopposite inclines on its under face fitting the top of the roof, it isobvious that it cannot be moved endwise without being raised and that itcannot be raised Without the disengagement of the supplemental cap L. Toremove the cap I with the supplemental cap L and 'the hook P, the nut onthe lower end of the bolt K may be removed, when the entire cap and hookmay be removed vertically together. When the nut is screwed up on theunder side of the ridgetimber, the parts are held tightly.

What I claim as my invention is- 1. In a car-roof,a metallic platehaving upon its edge a double spring-hook and a complementary platehaving upon its edge an upwardly-projecting rib or flange,complementarily shaped, with which the spring-hook of thefirst-mentioned plate is adapted to engage and be clamped thereon.

2. In a car-roof, the combination of a metallic plate having upon itsedge a flexible double spring-hook and a complementary metallic platehaving upon its edge a complementary spring-flange.

3. In a car-roof, the combination of a metallic plate having upon itsedge a flexible double hook and a complementary plate having upon itsedge a complementary flange formed with a gutter therein.

4. In a car-roof, the combination of a metallic plate having a doublespring-hook upon its edge, of a complementary plate having acomplementary flange upon its edge with which the first-mentioned hookis adapted to engage, said flange being composed of the inverted-troughsections a a, and the gutter 1) between.

5. In acar-roof, the combination of metallic plates joined at the peakand at their sides, of a peak-cap for the meeting corners of theadjacent sections having channels formed in its under face and anopening therein through which the securing-bolt is adapted to pass, anda supplemental cap detachably arranged upon the peak-cap and coveringthe bolt-opening in the latter.

6. In a car-roof, the combination of the metallic plates securedtogether along the peak and at the sides of the plates and a cap for themeeting corners of the adjacent sections having a bolt-hole centrallytherethrough, of a supplemental cap detaohably engaging the cap-plateand covering the bolt-hole, and a connecting member joining thedetachable cap with the sleeper for the running-boards.

7. In a car-roof, the combination with the metallic plates, of a seriesof apertured peakcaps arranged over the meeting corners of adjacentsections, supplemental caps detachably arranged over the openings in thepeak caps, sleepers for the running-boards, and connections between thesleepers and the supplemental caps.

8. In acar-roof, the combination with a metallic roof-sheathing, of aseries of caps arranged over the corners of the adjacent sections, asupplemental cap detachably secured thereto and covering the bolt holetherethrough and a hook thereon engaging the sleepers for therunning-boards.

9. In a car-roof, the combination of the metallic sheathing, of amultiple of connected metallic roof-sections thereon, a series of capsarranged over the meeting corners of adjacent sections, each cap havinga bolt-hole formed therein, a dovetail flange upon the caps, asupplemental cap having a dovetail recess engaging said dovetail flangesand a hook on said supplemental caps adapted to engage the sleepers forthe running-boards.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM J. MoCULLEY.
